Pressure gauge is a monitoring function, that is, the detection of system pressure, density relay is on the one hand is to monitor the change of system pressure, on the other hand is to control and protect the function, density relay can be set in different pressure states of the open and close signal contact. There are usually alarm contacts and latching contacts, and the pressure gauge is without contacts, which is the difference between the two. Density relays, pressure relays with temperatur

After the SF6 Density micro-water online monitoring system (Winfoss-S6) micro-water monitoring unit is officially connected to the gas chamber, because the SF6 gas in the gas chamber needs to gradually reach a dynamic balance with the gas in the cavity of the newly connected equipment, the micro-water value displayed by the monitoring unit will appear a change curve of first rising and then decreasing, and slowly decrease to the micro-water value of SF6 gas in the gas chamber. Under normal circu

1, ppm is a specific gravity unit, used for gas composition measurement. It is divided into ppmv and ppmw, respectively corresponding to the volume ratio and mass ratio, and all belong to absolute units. Volume ratio refers to the volume number of a certain pure gas contained in the unit reference gas, ppmv is one part per million, that is, 1uL/L. For example, after 1 liter of air is injected with 1 ml of pure SF6 gas to make it uniform, we call the SF6 concentration in this container 1000 ppmv.

SF6 gas is a molecular gas with many atoms. The decomposition and ionization of SF6 gas at high arc temperature is very complicated. The arc center part of SF6 gas has low thermal conductivity, high temperature and high conductivity. The outer flame part has high thermal conductivity, low temperature and small conductivity, so the arc current is almost concentrated in the arc center part. As a result, a very thin, bright arc can be seen in SF6 gas, and the external flame site is almost invisible

[Winfoss- China] There are many factors that the leader does not take the initiative to communicate with you, or because of the leadership time problem, or because of the leadership style problem, if you do not take the initiative to communicate with the leader, you may lose the opportunity for the leader to understand you, or lose the opportunity for you to show your talent, you will miss a great opportunity for development, because the leader does not understand you, He wouldn't recommend you
